Integrated Battery Feature (IBF)

Removal
Attention: This process requires:
v The use of a lift tool (part number 09P2481) and lift-plate assembly tool (part number 11P4369).
v The lift tool wheels must be chocked to prevent it from moving during the operation. The frame must not
be on its casters, and the leveling pads must be engaged to prevent the frame from moving during the
operation.
The IBFs (if installed) are mounted under the media subsystem.
1. Locate the IBF to be replaced.
2. Press the green Start Service button on the UEPO switch.
3. Turn off the IBF circuit breaker (to the right).
4. Unplug the battery cable from the front of the IBF, and remove the 7-mm M5 screw (closest to the
connector) that is holding the cable to the frame. This action allows the cable to move so that the IBF
can be removed.
5. Remove the two mounting bolts from the guide rails and retain for reuse during the replacement
procedure.
6. Read all safety instructions before performing this operation. Unpack the lift tool and follow assembly
instructions included with the tool. Inspect the tool for damage (do not perform the removal procedure
with a damaged lift tool). Replace the blue lift plate with the orange lift plate (part number 11P4369).
Orient the two round holes in the lift plate to the side of the lift tool that will be closest to the frame.
Install the wheel chocks and engage the brake.
7. Raise the plate to a height such that the lift plate is just below the base of the IBF you are removing.
Release the pins on the lift plate and fully extend the center portion of the plate toward the IBF and
lock it in place. Release the pins on the extender arms and position them on both left and right side.
The arms must fit around the frame extenders and lock in place (do not adjust the lift tool after these
arms are locked in place).
8. One person should gently pull and guide the IBF onto the lift plate. The IBF must be removed far
enough to clear the front face of the frame. Retract the extender arms and center portion of lift plate.
Note: Ensure that the IBF is in the center of the lift plate.
9. Lower the IBF to the bottom position of the lift tool.
10. Remove the wheel chocks and release the brake. Flip the crank handle 180 degrees. Carefully move
the lift tool with the IBF to the staging area. The brake and wheel chocks must be in place when
transferring the IBF to or from the packaging material.
